Mod1&2: Science and Chemistry of Life
homeostasis
The study of the interactions between living and nonliving things.
ecology
The study of cells.
The science that studies how characteristics are passed from parent to offspring.
A 2-letter set that represents the alleles an organism possesses for a certain trait.
genotype
All the processes together by which an organism converts energy and matter to use that energy to sustain its life functions.
metabolism
Evaporation of water from the leaves of a plant.
transpiration
A tiny cellular structure that carries out a specific function necessary for the cell to survive.
organelle
The basic unit of heredity; a section of DNA that contains the code to produce a trait.
gene
A genotype in which both alleles are identical, ie:hh
homozygous genotype
This regulates the amount of carbon in ecosystems, by keeping careful track of carbon dioxide.
the carbon cycle
All cells have these structures in common.
dna, plasma membrane, cytoplasm, ribosomes
The process by which two identical DNA molecules are produced from one original DNA molecule
DNA replication
The father of modern genetics.
Gregor Mendel
The basic building blocks on proteins each containing a carboxyl group and an amino group
amino acids
The close relationship between species where at least one benefits, and describe the relationships within its 3 specific types.
symbiosis
1. mutualism- all benefit
2. commensalism- 1 helped, other neutral
3. parasitism- 1 benefits, other harmed
These are the stages of cellular respiration.
1. glycolysis (glucose splits)
2. link reaction (coenzyme A attached)
3. krebs cycle (breakdown of acid, energy release)
List the steps of mitosis.
prophase
metaphase
anaphase
telophase
cytokinesis
The observable expression of an organism's genes.
catalysts
This tells you the maximum amount of energy available in an ecosystem. measuring the rate at which producers make biomass.
primary productivity
State the cell theory.
1. all organisms are made of cells
2. cells are the basic unit of structure
3. cells arise from existing cells
In this step of protein synthesis, nucleotide base sequence "language" in RNA becomes amino acid sequence "language" in protein.
translation
Using a Punnett square, find the possible genotypes and phenotypes of parent plants: Ttff with ttFf (T is tall, F is purple, tt is short, and ff is white flowers).
6/16 Ttff (tall and white)
6/16 ttff (short and white)
2/16 TtFf (tall and purple)
2/16 ttFf (short and purple)
